摘要
山区径流式小型水电站多采用低坝引水，常常不太重视防沙设计，致使大量推移质泥沙进入渠道，影响电站经济运行。全州县鹞子江电站引水枢纽设计，根据不同条件，采取沉沙槽、冲沙闸等工程措施来解决渠道淤积问题。电站建成后已运行３年，达到了设计的预期目的。
In mountain area, the small hydropower stations without storage mostly use low dam to diverse, but designer usually don't pay attention to sediment control design.Lots of sediment get into channel and affect the station's economic operation.According to different conditions, the Yaozijiang hydropower station diversion pivot designing uses engineering countermeasure, such as desanding trap, desilting sluice,etc., to solve canal head silting problem.The Yaozijiang hydropower station have been operated for three years and achieves the desired results.
